Need precise flow control for air, water, oil, or gas lines? This TAISHER needle valve is built tough for the job. It's made from forged 304 stainless steel, which means it's highly corrosion-resistant, durable, and has low magnetic permeability. The connection is 1/4\ Female NPT (remember, NPT is a thread standard, not the exact diameter). It can handle a maximum working pressure of 2000 PSI and temperatures from -4°F to 248°F – specs that beat many standard valves on the market. It's about 20% thicker than typical valves for extra strength. The smooth edges and precision manufacturing make installation easier. An industrial-grade component perfect for DIY projects, workshops, or professional plumbing/air systems where reliable, fine-tuned control is key.
